10 The status of the sensors defines the detection zone numbers
(bits 0-2 of the cyclic output data). This defines which detection
and warning zone is active. Possible activation in this example:
■ zone pair detection zone 1 and warning zone 1 or
■ zone pair detection zone 2 and warning zone 2
If you want to expand the example in such a way as to work
with three or (maximum) four zone pairs, you can use the already
prepared program sequences (further information
given on page 311).
The sensors for switching the detection zones are directed to
a fail-safe input module of the ET 200S. In case of a failure at
this input module, switching between the detection zones is
not possible anymore. This error is detected and sets the failsafe
output module into fail-safe mode (indicator light is
switched off).
Reaction times
For calculating the max. reaction time of your F-system please
use the Excel file (Cotia table), which is available for S7 Distributed
Safety V 5.3. This file is available on the internet:

Prepared detection and warning zones
Apart from the STEP 7 project, both prepared zone pairs
(SF1-WF1, SF2-WF2) are also available as a separate download
file. Chapter 4 describes how to load these configuration data
into the LS4. The prepared zone pairs are illustrated below for
a first impression of the parameterization software LS4Soft.
Note
The contours of the detection and warning zones used
in the example project are rectangles. The software
LS4Soft also offers the possibility of perameterizing
other contours (e.g. semi circles) as zone delimiters.
